Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620784, here are decompositions:

  • 37 + 8620747 = 8620784
  • 61 + 8620723 = 8620784
  • 97 + 8620687 = 8620784
  • 163 + 8620621 = 8620784
  • 181 + 8620603 = 8620784
  • 241 + 8620543 = 8620784
  • 457 + 8620327 = 8620784
  • 643 + 8620141 = 8620784

Showing the first eight; more decompositions exist.
